Previously the parameters were not ignored so */*;q=0.8 was not identified as accepting */*. As a result, the most recent producible content type was returned rather than the default. This commit updates the argument resolver to ignore parameters. The default content type is now produced in response to a request that accepts */*, irrespective of its parameters. Fixes gh-28446 |

= Spring Boot - Actuator Spring Boot Actuator includes a number of additional features to help you monitor and manage your application when it's pushed to production. You can choose to manage and monitor your application using HTTP or JMX endpoints. Auditing, health and metrics gathering can be automatically applied to your application. The https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/#production-ready[user guide] covers the features in more detail. == Enabling the Actuator The recommended way to enable the features is to add a dependency to the `spring-boot-starter-actuator` '`Starter`'. To add the actuator to a Maven-based project, add the following '`Starter`' dependency: [source,xml,indent=0] ---- <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-actuator</artifactId> </dependency> </dependencies> ---- For Gradle, use the following declaration: [indent=0] ---- dependencies { implementation 'org.springframework.boot:spring-boot-starter-actuator' } ---- == Features * **Endpoints** Actuator endpoints allow you to monitor and interact with your application. Spring Boot includes a number of built-in endpoints and you can also add your own. For example the `health` endpoint provides basic application health information. Run up a basic application and look at `/actuator/health`. * **Metrics** Spring Boot Actuator provides dimensional metrics by integrating with https://micrometer.io[Micrometer]. * **Audit** Spring Boot Actuator has a flexible audit framework that will publish events to an `AuditEventRepository`. Once Spring Security is in play it automatically publishes authentication events by default. This can be very useful for reporting, and also to implement a lock-out policy based on authentication failures.
